[xwiki-users] Changing properties on a class

Hi all, I have a class with a property which is a long and i want to change it to float or double, but I got a 'A problem occured while trying to service your request. Please contact the support if this happens again. ' error when i try to save the change I think that maybe that comes from the fact that I have some entities of this class in the database. Is this a bug ? If I remove all the entities of this class, will I be able to make the change ? Hope somebody can help.
